PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimetre-wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

Computer Tuned

To minimise weight, Giant engineers use FEA (Finite Element Analysis) to develop a strategic layup
schedule of Uni-Directional and woven composite. This ensures the precise amount of composite material where a frame requires it and minimises excess material where the structure doesn’t.

Overview

It's simple: the more comfortable you are in the saddle, the better you can perform. Climb, descend, sprint - all day long.

With its longer wheelbase and slightly taller headtube for endurance positioning, Defy Composite gives you a lightweight, smooth riding feel that makes the road disappear. Crafted from Giant’s Composite frame material, it features innovative technologies including the PowerCore bottom bracket and OverDrive headtube for stiff pedalling efficiency and razor-sharp handling. The frame is also RideSense-ready, for use with Giant’s wireless ANT+ data device.

Weight

The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All Giant bikes are designed for best-in-class weight and ride quality.
